Find the Equalization effect and switch from Draw Curves to Graphic EQ.A low pass filter helps if your audio is too high-pitched, while a high pass filter comes in handy if the audio sounds too low or too muffled. They are located in the bottom half of the Effects menu. Depending on your current sound pitch inside of the file, you might need to use a low pass or a high pass filter.The main thing you should do is change up the ratio, but you can also change up the noise floor and threshold if necessary. Find the compressor in the Effects menu.If turning up noise reduction decreases the volume, go to the effects menu and choose Amplify to increase the volume.Increasing the Noise reduction slider should greatly improve audio quality.Open the Effect menu at the top of the screen.

If you want to edit the whole file, press Ctrl+A on Windows or Command+A on Mac. You can do this by clicking on one end of the segment and dragging the mouse until you reach the other. Select the segment of the audio file you’d like to edit.Click on the file you want to edit, then click Open.At the bottom of the window, change Files of type to All supported types. Reducing Echo Without a Plug-InĪfter downloading and starting Audacity, follow these steps: Do you like to record internet audio or YouTube Clips? you could be causing feedback internal to the computer and causing the slow, weird computer version of feedback like getting the band’s microphone at a club too close to the speakers.With that in mind, let’s take a look at how you can remove echo in Audacity with and without a plug-in. Audacity does not apply effects or filters in real time or during recording Root around in Windows Control Panels and see if you can find a service that does noise reduction or echo reduction. You have to change the cable a bit, but those are readily available.ĭo you leave Skype running in the background while you do audio production? Skype is a conferencing tool, right? Skype is famous for grabbing your sound system with white knuckles and not letting go. This is an inexpensive USB stereo, high-level audio interface I use. Stereo Line can be as much as 1000 times more powerful than a microphone signal. Since you have WinXP, you may just be beating up your Mic-In connection so bad it starts falling over. This usually kills music but leaves voices alone. If you didn’t notice any harsh, crunchy distortion, you may have gotten lucky.Īs far as the other problem goes, newer Windows like Vista, Win7 and Win8 default to conference mode “Windows Enhanced Services” and automatically apply noise reduction and echo suppression, sometimes whether you want it or not. Some computers can switch one connection between low-level mono Mic-In and High-Level Stereo Line-In. It’s designed to do this pretty much exclusively. Headphone or Line-Out on a sound device is very seriously incompatible with the Mic-In on a Windows Laptop. Is there some kind of auto-setting that I need to deactivate? Is it to do with the digital audio recorder? If so, any way I can correct for that? I’ve run numerous tests and it happens every time. Again, I’ve used Audacity a lot, for both music and straight voice, and this is not a problem I’ve encountered before. NR must be applied very sparingly because a lot of vocal subtleties can be lost e.g., f someone’s speaking volume trails off at the end of their sentences, the last several words are inaudible.īut this NR is occurring automatically. The voices are mostly audible but so much of the ambience has been removed that it sometimes devolves into digital blips and bleeps.įor transcribing the human voice, it’s better to have more ambient noise rather than less (provided it’s simple room tone, not jackhammer noise). But then the sound automatically – i.e., without any intervention from me – turns into what sounds like an overly-noise-reduced track. What happens is that the first 3-4 seconds of the Audacity recording play back with normal hiss and ambient sound, as heard through the DAR itself.

I’ve run tests to adjust both output and input volume levels. I’m feeding in audio of interviews (no music, just voice) from a digital audio recorder through the microphone jack. I’ve used Audacity many times in the past and I’m encountering something new to me. I just downloaded Audacity 2.0.5 on a Lenovo Thinkpad T400 running Windows XP Professional.
